Member Enumeration Documentation

enum SkClipStack::Element::Type

Enumerator

kEmpty_Type

This element makes the clip empty (regardless of previous elements).

This element combines a rect with the current clip using a set operation

kRect_Type

This element combines a round-rect with the current clip using a set operation.

kRRect_Type

This element combines a path with the current clip using a set operation.

Member Function Documentation

bool SkClipStack::Element::contains ( const SkRect & rect ) const

inline

Conservatively checks whether the clip shape contains the rect param.

(Whether the shape is inverse filled is not considered.)

void SkClipStack::Element::dump ( ) const

Dumps the element to SkDebugf.

This is intended for Skia development debugging Don't rely on the existence of this function or the formatting of its output.

const SkRect& SkClipStack::Element::getBounds ( ) const

inline

Gets the bounds of the clip element, either the rect or path bounds.

(Whether the shape is inverse filled is not considered.)

int32_t SkClipStack::Element::getGenID ( ) const

inline

The GenID can be used by clip stack clients to cache representations of the clip.

The ID corresponds to the set of clip elements up to and including this element within the stack not to the element itself. That is the same clip path in different stacks will have a different ID since the elements produce different clip result in the context of their stacks.

bool SkClipStack::Element::isAA ( ) const

inline

If getType() is not kEmpty this indicates whether the clip shape should be anti-aliased when it is rasterized.

Inverts the fill of the clip shape. Note that a kEmpty element remains kEmpty.
